Chromatid nyob rau hauv ib chromosome nyob qhov twg?
A chromatid yog ib qho condensed DNA subunit ntawm chromosome. Ob tug chromatids ntawm ib tug duplicated chromosome yog tuav ua ke nyob rau hauv ib cheeb tsam ntawm DNA hu ua the centromere (saib daim duab hauv qab).
Chromatid yog dab tsi?
A chromatid (Greek khrōmat- 'xim' + -id) yog ib nrab ntawm cov chromosome duplicated. Ua ntej replication, ib chromosome yog tsim los ntawm ib tug DNA molecule. Hauv kev rov ua dua, DNA molecule raug theej, thiab ob lub molecules hu ua chromatids.
Puas yog chromatid ib leeg lossis ob txoj hlua?
Txhua chromatid muaj ib ob-stranded DNA molecule.
Puas yog chromosome muaj ib chromatid?
Chromosome muaj ib chromatid thiab yog decondensed (ntev thiab hlua zoo li). Cov DNA tau theej. Lub chromosome tam sim no muaj ob tug muam chromatids, uas txuas nrog cov proteins hu ua cohesins.
